Ballast Water Risk Assessment Process
In this phase of the DSS process RA is undertaken to provide for adequate BWM
based on the acceptability of the risk level assessed. 6 If the level of risk is accept-
able, then the vessel will be cleared to proceed without conducting BWM. However
she may still be selected for the verifi cation process. If the level of risk is not accept-
able, the vessel will need to undergo a BWM procedure (see Fig. 10 ).
Decision 4: Is Risk Acceptable?
The risk assessment process is in detail described in chapter “ Risk Assessment in
Ballast Water Management ” and covers RA background, principles, RA end points,
RA methods, RA errors and the application of RA under the BWM Convention.
6 this is dependent on the port State environmental legislation, and the perception, values and ethics
of the assessors.
